Three Space Foundation Indexes provide an easy-to-access and easy-to-understand mechanism for gauging the financial performance of the U.S. space industry.

The Space Foundation Index (SFI) is the original index created by the Space Foundation to track the breadth and depth of the space industry in the U.S. public markets. Market tracking for the SFI was initiated on June 30, 2005, at a level of 100, enabling quick determination of the percentage change in value since inception.

The Space Foundation Infrastructure Index (SFII) tracks companies in the U.S. public markets that derive significant revenues from the sale of space-related hardware, software and integration services for space-related applications such as the manufacturing of satellites and launch vehicles or ground-based items such as terminals and chipsets. It was initiated with a level of 100 as of June 30, 2007.

The Space Foundation Services Index (SFSI) tracks companies in the U.S. public markets that derive significant revenues from services that depend heavily on space assets for collection, transmission and/or provisioning, such as those related to satellite broadcast, communications and remote sensing. It was initiated with a level of 100 as of June 30, 2007.

Index Composition

The Space Foundation Index is composed of all companies represented in the Space Foundation Infrastructure Index and the Space Foundation Services Index. Some companies are listed in both sub-indexes because they conduct operations in multiple sectors.

Selection and Methodology

The Space Foundation Indexes are modified market capitalization-weighted indexes of representative space companies listed on U.S. market exchanges. Component companies are selected based upon an evaluation of several criteria, including percentage of revenues attributable to space-related products and services, market capitalization, and trading volume.

Consideration is also given to providing diverse representation across various space-related markets. Space revenues include launch vehicle, satellite and related ground segment manufacturing of components and systems; satellite communication services and capacity leasing; space-related positioning and remote sensing data and services and related equipment (including GPS chipsets); and space-related software, operations and support services. Space revenue estimates are based upon a review of multiple sources, including Space News Top 50 lists, company websites and SEC filings, as well as internal experience. The Space Foundation Indexes are prepared by ISDR Consulting, LLC, on behalf of the Space Foundation.

Changes in the index values are driven by changes in the market capitalization of the component companies (price multiplied by number of shares outstanding of each company). The contributions of certain component companies' market capitalization to a given index have been discounted to adjust for lower percentage of revenues attributable to the space-related products and services that are the focus of a given index. Certain component companies' market capitalization contributions to a given index have also been adjusted to discount for size. The level of the indexes are not directly altered by stock splits, stock dividends or trading halts, nor are they affected by new listings, additional issuances, delistings or suspensions.
